LIQUID-SUPPLYING MEANS FOR A. ROTAIABLE BODY.

Specification of Letters Patent. I

Patented Nov. 10, 1914.

Application filed October 5, 1912. Serial No. 724,154.

To all whom it may concern Be it known that I, HERMAN JUILrs, a citizen of the United States, residing at lVhite Oak, in the county of Brown and State of Ohio, have invented certain new and useful Improvements in Liquid-Supplying Means for a Rotatable Body, of which the following is a specification, reference being had to the accompanying drawings. I

This invention relates to certain improvements in means for supplying liquid to a rotatable body and has relation more particularly to a device of this general character: especially designed and adapted for use in connection with a mixer; and the object of the invention is to provide a device of this general character having novel and improved means whereby the supply may be regulated or entirely out off, as the necessities of practice may require.

Another object of the invention is to provide a device of the above character wherein the supply of water used to mix the concrete is evenly distributed through the material so as to assure an even mixture of the I concrete.

With the above and other objects in view, the lnvention consists in the novel features of constructlon and the combination and are rangement of parts hereinafter more fully described, pointed out in the claim and shown 1n the accompanying drawings, lIl

which Figure 1 is a vertical sectional view taken through a mixer, disclosing a liquid supplying means for a rotatable body, constructed in accordance with an embodiment of my invention; Fig. 2 is a detail perspective View of the adjustable sleeve herein included; and

. Fig. 3 is a detail perspective view of one cured to the cross pieces by means of the U-bolts 5 and is provided upon its lower side with a plurality of spaced openings 6 which are adapted to register with a plurality of similar openings 7 formed in the sleeve 8 which is slidably mounted upon the pipe 4.

Rotatably mounted upon the collars 11 is the mixing drum 9 which is provided at each end with a bracket 10 adapted to be rotated upon the collar 11 arranged at each end of the drum and mounted upon the pipe 41. Se cared to one of the brackets 10 at one end of the drum is a gear 12 which is adapted to mesh with asimilar gear 13 mounted upon the inner end of the operating shaft 14.

The sleeve 8 is provided at one end with the elongated recesses 15 which extend inwardly from the end of the pipe and are adapted to receive the inwardly extending webs 15 formed upon one end of one of the collars 11. to limit the sliding movement of the sleeve 8 so that the openings 7 therein will be brought into alinement with the openings 6 in the pipe 4. This operation is accomplished by means of a lever 16, the lower end of which is pivotally mounted upon the bracket 14 and having its intermediate portion pivotally mounted upon'the lugs 17 formed integral with the collar 18 which is fitted over the end of the sleeve 8.

Thus it will be seen that by the manipulation of the lever 16, the sleeve 8 may be reciprocated upon the pipe 4.

The drum 9 is provided with a suitable opening through which the material is placed therein, said opening being suitably closed by means of the cover 19.

Mounted upon the frame work and arranged above the drum and to one side thereof is a suitable hopper 26, the lower end of which is normally closed by means of the swinging chute 27. The chute 2'? is to be of sufficient length so as to extend well into the drum when lowered to allow the contents of the hopper to flow entirely into the drum and not permit the same to drop therein from any distance thus preventing the creation. of dust, which generally arises if the material is dropped from any distance.

Suitably mounted above the drum 9 is the water tank 29 which is adapted to contain sufficient amount ofwater to thoroughly mix a predetermined amount of material contained in the hopper. Arranged within the tank 29 is a float 30 which is connected to'the lower end of the rod 31, the upper end of which is pivotally connected to a pivotally mounted lever 32, the other end of said lever being suitably connected to the upper end of the operatingrod 33. The'opcrating rod 33 is connected to the short end of a pivoted arrow 34,- which is adapted to operate upon the dial 35. The float 30 is adjustably connected to the rod 81 by means of a gage pin 36 adapted to be inserted through the openings 37 formed in the rod 31 and the stem 38 of the float. Thus it will be seen that in order to provide a uniform amount of water with respect to the material in the hopper 26, the gage pin 37 is to be adjusted to raise or lower the float 30.

In order to properly determine the sufficient amount of water necessary to thoroughly mix the concrete properly, a trial is made so as to determine how much water is necessary to moisten the batch properly, the gage pin 37 is then set so as to raise or lower the float 30 a sufficient distance so that when there is enough water in the tank the arrow 39% will point toward the word Full. Thus it will be seen that after the necessary amount of water has been found and the gage pin set, the work will be absolutely uniform until a different amount of material is used, when a new trial will have to be made. The water in the tank 29 is conveyed to the drum 9 by means of a pipe 39 extending downhardly from the tank and provided at its lower end with a two way connection 450 which is suitably connected to each end of the pipe l by means of the pipes 4-1, and it will be readily seen that by having half of the supply of water entering each end of the pipe l, the water will pass through the openings 6 and 7 into the drum at each end thereof in equal quantities so as to thoroughly moisten the entire batch which has been placed in the drum.

In the operation of my improved mixer, a predetermined amount of material is placed within the hopper 26, the chute 27 is then lowered to allow the material to pass into the drum 9. After the material has been deposited in the drum, the drum is then rotated to start the mixing of the material. After the dry material has been mixed, the water from the tank 29 is turned into the pipe l by means of the valve 42, the water entering each end of the pipe s in an equal. amount so that when it passes out through the openings 6 and 7 of the pipe 4 and sleeve 8, respectively, it will thoroughly mix with the material in the drum, the water flowing through the openings will prevent the holes from getting clogged with the dry material. As soon as the float 30 reaches the bottom of the tank 29, the arrow will point to the word Empty, and the sleeve 8 will then be shifted back into its normal position so as to prevent the clogging of the openings therein by means of the material within the drum.

From the foregoing description, it is thought to be obvious that a liquid supplying means for a rotatable body constructed in accordance with an embodiment of my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and by reason of the effectiveness with which it performs its functions, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

hat I claim is A device of the character described comprising a frame, a perforate pipe supported by such frame, a similarly perforated sleeve surrounding the pipe and adapted for end wise movement thereon, the perforations in said pipe and sleeve registering when the sleeve is at the limit of its movement in one direction, said sleeve being provided with open ended slots in one of its extremities, a bushing surrounding the sleeve and having lugs formed upon its inner face, said lugs extending into the open ended slots of the sleeve, a crum rotatably mounted on the sleeve, a bracket on an end of the drum rotatably engaging the bushing, a collar surrounding and rigidly secured to the slotted end of the sleeve, and means operatively connected with the collar to impart endwise movement to said sleeve, contact by said collar with the bushing limiting the movement of the sleeve in one direction, the movement of the sleeve in the opposite direction being limited by the 0011- tact of the inwardly extending lugs and the inner ends of said slots.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
